The scatter plot shows the number of pumpkins that have been picked on the farm during the month of October:
A scatter plot with points showing an upward trend with points that are moderately spread out from a line of best fit. The y axis is labeled Number of Pumpkins and the x axis is labeled Days in October
Part A: Using computer software, a correlation coefficient of r = 0.51 was calculated. Based on the scatter plot, is that an accurate value for this data? Why or why not? (5 points)
Part B: Instead of comparing the number of pumpkins picked and the day in October, write a scenario that would be a causal relationship for pumpkins picked on the farm. (5 points)
Answers
Part A: The correlation coefficient of r = 0.51 is accurate based on the scatter plot given.
Part B: A scenario that would be a causal relationship can be quantity of fertilizer used vs kg of pumpkins picked on the farm.
What is a Scatter Plot?The association between two variables that are correlated can be shown by a scatter plot which has a trendline along which the data points are located.
If the trendline slopes upwards from the left to the right, it shows a positive correlation and vice versa.
Also, if the farther the data points are to each other along the trendline, the farther is it the correlation coefficient, r, is from 1 or -1. If they are moderately apart,, the correlation coefficient would be somewhere around 0.5/-0.5 and 0.65/-0.65, as the case may be.
Part A:
The correlation coefficient of r = 0.51 is accurate based on the scatter plot given.
Part B:
A scenario that would be a causal relationship can be quantity of fertilizer used vs kg of pumpkins picked on the farm.

[tex]43/100[/tex]
Step-by-step explanation:
First, make both of the denominators into 100.
Then, 3/10 would be 30/100.
Finally, you can add them to get 43/100.
Make both denominators into 100 so that means 3/10 would be 30/100 then you add both so 30/100+ 13/100 only adding the numerators so it will equal 43/100

From an 18-pound cut of meat, Mr. Rand cuts off steaks weighting 1 pound 15 ounces, 3 1/8 pounds, and 4 1/2 pounds. He divides up the rest into 9-ounces patties and sells them at 3 for $3.12. How much money does he receive for the patties?
Answers
Answer is in the picture
The amount of money received by him will be $15.60.
What is an expression?Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division
The amount will be calculated as follows:-
The cut off amount = 18 - ( 1(15/16) -3(1/8)-4(1/2) = 8(7/16)
Now 16 ounces make a pound so divide by 16 we get:-
(135/16) ÷ ( 9 / 16 ) = ( 135/16 ) x ( 16 / 9 ) = 15
Dividing 15 by 3 we get 5 packs of 3 patties for $3.12
So amount = 3.12 x 5 = $15.60
Therefore the amount of money received by him will be $15.60.

Rosena bought an 8 pack of donuts to share with her friend at school. The donuts cost $28.00 all together. What is the unit rate for the donuts in $/donuts?
Answers
Answer:
$3.50/donut
Step-by-step explanation:
Since Rosena bought an 8-pack of donuts for $28.00, we can say that the price of $28.00 corresponds with this pack.
The unit rate represents the price per donut, assuming a constant proportion.
The pack that Rosena bought contains 8 donuts. Therefore, to find the price of one donut, divide the price that corresponds with the 8-donut pack by 8, because [tex]8\div 8=1[/tex].
The price of the 8-pack of donuts was [tex]\$28.00[/tex]. Diving by 8, we have:
[tex]\frac{\$28.00}{8}=\boxed{\$3.50}[/tex]
Therefore, the unit rate for the donuts is $3.50/donut.
Answer:
$3.5

In the figure shown, line AB is parallel to line CD.
Part A: What is the measure of angle x? Show your work. (5 points)
Part B: Explain how you found the measure of angle x by identifying the angle relationships that you used along the transversal. (5 points)
Answers
Answer:
Part A
x is 46°
Part B
Alternate angles are angles that are in relatively opposite locations relative to a transversal
Step-by-step explanation:
Part A
∠DRP = 110° (Given)
∠QPA = 64° (Given)
∠QPR =
Given that AB is parallel to CD, we have;
∠DRP is congruent to ∠APR (Alternate angles to a transversal RP of parallel lines AB and CD)
Therefore, ∠APR = 115°
∠APR = ∠QPA + ∠QPR (Angle addition postulate)
∴ 115° = 64° + ∠QPR
∠QPR = 110° - 64° = 46°
x = 46°
Part B.
Given that AB is parallel to CD, the lines common (that intersects) both lines are the transversal lines
The angles formed between the parallel lines and the transversal lines have special relationships based on their position with respect to each other
In the question, the angle 110° given between CD and the transversal RP, is found to at an alternate position to the angle ∠APR between the same transversal RP and AB and given that alternate angles are always equal, angle ∠APR is therefore also equal to 110°.
